The project for the propagation and conservation of the local flora of Menorca was developed between 2000 and 2003 with an educational and informative purpose.
It consisted of a representation of the local plant life which the visitor can see along the path around the old quarries, making use of the diversity of existing areas for a specific design of each quarry.
Furthermore, the project involved the creation of a nursery where production of local plants is undertaken in order to supply the botanical tour and other gardening projects at the quarries.

Starting in 2006, the original Botanical tour was extended and became the Biodiversity tour, a project in which information panels were placed all along the route around the quarries; this tour consists of four subtours: plants, animals, geology and ethnology.
